We divide 354510 by 15
We're looking to find how many times 15 goes into 354510.

On to step 1:
15 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 15

Let's proceed to step 2:
35 divided by 15 is 2 with a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 30 from 35, we get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 15

Advancing to step 3:
15 can be fit into 54 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtracting 45 from 54 leaves us with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 15

Going ahead to step 4:
15 goes into 95 6 times with a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 236.0
Subtract 90 from 95 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 15

On to step 5:
51 divided by 15 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 2363.0
Subtracting 45 from 51 leaves us with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 15

Moving on to step 6:
60 divided by 15 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 23634.0
Subtract 60 from 60 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
15 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 23634.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 23634.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 23634.0 and a remainder of 0.0.
